Magic - Corruption
Corruption affects the Body, Mind, and Spirit of the caster. This relates to changes on the character’s body as they slowly turn into a demon, which happens at 100% corruption, or by chance on death. The changes relate to the type of demon being turned into, which can have various visual clues.
Also, spells cast while having corruption have a chance to become Chaotic equal to the amount of corruption the user has (so 10% corruption is 10% for Chaos Magic).
Upon Death, a character has a chance equal to their corruption to turn into a Demon immediately, forever rendering them demonic.
Through Rigorous Training, you can gain Corruption Resistance. This training requires you to permanently sacrifice 1 Constitution, and is done at the end of 4 weeks training which costs 20,000gp in healing costs. The training involves constantly overusing spells in small doses and rehealing your body, permanently causing damage to your body to gain some small measure of resistance against Corruption.
This resistance causes you to take half as much, rounded down, in any occasion where you would take Corruption.
For Example, lets say you can cast 6th level spells, but decide to cast a 9th level spell. This would normally cause 30% Corruption, a huge blow, but instead only causes you 15% Corruption.
Also, in instances when you would take 1% Corruption, you take 0% instead.
Corruption can be healed in multiple means to a multitude of effect.
- Naturally: You heal at a rate of 1% per week if you have between 10% and 25% Corruption. Too much Corruption does not heal naturally whereas too little refuses to eek away entirely.
- Physical Medication: At a cost of about 50 gp per 1%, you can heal using natural physical means, assuming you have less than 50% Corruption. You can heal up to 2% per day using these means.
- Magical Cleansing: At a cost of about 100 gp per 1%, you can heal using magical means. You can cast this as a spell of 4th level (on the cleric and druid spell list) with material components equal to 80 gp per 1%. You can only heal this way if you have less than 75% Corruption. Ritual Spell.
- Corruptive Osmosis: With a varying cost depending on the caster (usually at least 200 gp per healed ), you can split Corruption with a spell caster. This allows you to pool both of your Corruption, plus 10, and split this among the two of you. This is an 8th level spell any caster can cast, and has no material component. Both parties must have at most 99% Corruption. Ritual Spell.
- Corruption Soothing: Sooth massive Corruption damage, causing your Corruption to lower to 25%. You must have at most 99% Corruption for this effect to work. You take 1 Constitution damage permanently. This is a 9th level Cleric and Druid spell that has a 10,000gp material component. This usually costs 15,000gp from a professional. Standard Action.
The effects that Corruption has on one’s body varies based upon what level of Corruption the user has gained. In general, the more Corruption gained, the more drastic the physical appearance, the more painful the injuries, and the more Chaotic their magic is. Here we cover what happens at various stages in terms of physical manifestations and bodily harm.
- 0-4 Corruption: Minor pain and brief skin irritation when causing the Corruption.
- 5-14 Corruption: Brief rashes of some color appear on the skin. This rash lasts longer depending on what level of Corruption you are at. 5 lasts for about 30 minutes, whereas 14 lasts for about 2 days.
- 15-34 Corruption: Rashes that last about 2 to 3 days, then disappear for about 3 hours and a new one appears elsewhere on the body. This will keep happening until the person is below 15 Corruption. The color of the rash is always the same for an individual, but differs from person to person.
- 35-49 Corruption: The rashes have gotten bigger, and can now appear in multiple locations. Minor changes begin to take root such as claws, webbed digits, sharp teeth, or different colored eyes. These minor changes have a chance to be permanent. Noone knows why.
- 50-69 Corruption: The rashes now take up about 25% of a person’s body, always appear in multiple locations, and there is always at least one rash on the body. This means the pain (which is greater at this point) is constant and on different parts of the body. More extreme changes begin to take root such as the growing of horns, growing or receding of hair, or gain or loss of weight uncontrollably. To a smaller degree, any of these effects could be permanent. This could mean smaller horns, different metabolism, or slightly more or less hair growth than normal.
- 70-89 Corruption: The rashes now take up over half of the body, and the pain has grown to be not only on the rashes, but a constant ache of the person’s bones and muscles. Drastic changes such as the forming of hooves and stubbing of wings begin to take place. Effects from this stage that could be permanent generally include possible broadening of shoulders or bigger, thicker toenails.
- 90-96 Corruption: The rashes now take up about 90% of the body, and pain extends into the mind and reaches drastic levels. For a number of months, the person is completely debilitated and can only cast magic. They cannot even move around during this time due to the pain. Wings that cannot be flown and entirely different legs or arms form during this period, causing even more pain. Scars from the rashes can develop all over the body and possibly appendage structures could remain in place. This could mean inverted knees, hooves, bendable arms, or spikes protruding from the body.
- 97-99 Corruption: This miniature stage reflects the literal changes to bone structure of the person as they shift size to match that of the demon. The pain is still very large and hard to bear. Hallucinations are almost constant during this stage and distinguishing friend from foe is difficult, and making the best decisions is hard especially with all of that magic in your control. The changes in size are never completely healed and generally people are slightly different heights than they were before. They may also continue to see hallucinations on occasion, but this effect is rarer.
- 100 Corruption: You have completely turned into a demon. There is no reversing this and you are in constant pain. Your mind and soul have also been corrupted, causing you to seek pain and suffering upon others. You lose control of the character (in fact you are likely still too debilitated to do anything for a few months even as a demon). The demon cannot die and instead is renewed in the Magic Well after a few minutes to relive their torture.
Chaos Magic applies to ALL spells, and ANY ability that is spell-like (comes from magic). This effect replaces the spell being cast.
